This invention relates to improvements in drilling mechanisms particularly adapted for use 1n coal mmes and has among other obects to provide a new and improved drilling mechanism and support therefor and-particularly one which may be supported on a mine locomotive, or a similar portable power device.

Other objects of my invention will appear from time to time as this specification proceeds. v

My invention may be more clearly understood with reference to the. accompanying drawings, wherein:

Figure 1 is a fragmentary side elevation of the drilling mechanism shown in Figure 3" with the drilling'mechanism in another position than that shown in Figure 3 Figure 5 is a fragmentary top plan view of the device shown in Figure 3 withparts broken away and in section to'more clearly show the details of my invention; and

Figure 6'is a rear elevation of the device shown in Figure 3 with parts broken away and in section to more clearly show the details of my invention.

- Referring now. 1n particular to Figures 1 and 2, my invention is'shown as applied to a mine locomotive 10 of an ordinary type. plurality of drilling mechanisms generally indicated at 11 are provided with arms 12, 12,

3 supported on and extending outwardly from each side of the forward portion of the locomotive. The arms 12, 12, may be constructed in any suitable manner but are herein shown as I-beams of an ordinary type and are pivotally mounted on brackets 13, 13, by

mechanism 11,

means of pivotal pins 14, ll. The arms 12, 12, are supported on their outer end-by means of adjustable supports 15,15,'engageable with the mine bottom and detachably connectible to said arms by any suitable means well known to the art to more-solidly support said arms while the drilling mechanisms 11, 11, are drilling holes in the mine wall. 1'

Means are provided to holdthe arms 12, 12, stationary in various desired pivotal positions with-respect to the locomotive frame which herein comprise a spacing rod 18' for each arm having hooked end portions which may engage one of a plurality of holes in" the arm 12 at one cnd and one of a plurality of holes in an angle 19 on the locomotive 10 at'its oppositesend. I A supporting means for the drilling generally indicated at 16,).is

adapted to be detachably mounted on each arm 12 and is slidable therealong for supporting the drilling mechanism 11 in any de-' sired position along the arm 12. The supporting means 16 includes a plate 20 adapted to rest on the top portion of the support ing arm 12 having strips 21, 21, bolted to r the lower portion thereof and abutting thev under portion of the flange of the I-beam which comprises the supporting arm 12 to form a holding means for the plate 20 on the supporting arm 12 so said plate may be slidably supported on'said arm. A plate 23 is pivotally mounted on the plate 20 by means of a pivot pin 24'to move on said plate about a vertical axis. An ear 25 projects upwardly from one end and has av threaded member 26 pivoted there-- on. Likewise an ear 2'? projects upwardly from theopposite end of the plate 23and has a threaded member 28 pivoted thereon.

A supporting member 30 serves to support the drilling mechanism 11 and isadjustably supported on the ears 25 and 27 by means of the threaded members 26 and 28. Arms 31, 31, project upwardly from opposite ends of the supporting wardly projecting lugs 32 attached thereto at the top portion thereof by anysuitable means, said holding means being herein shown as a cap screw of a usual type.

of the plate 23 a member 30. and have inj Threaded rods 33 pass through the lugs 32 and are threaded within the threaded members 26 and 28 respectively. Collars 34, 34, abut the lower portion of the lugs 32, 32, and are held from movement along the threaded rods 33, 33, by any suitable means, said collars herein shown being preferably welded to the threaded rods 33, so that the arms 31, 31, will be raised or lowered as the threaded rods 33, 33, are rotated in one direction or the other. Handles 40, 40, are provided to rotate the rods 33, 33, to raise or lower the supporting member 30.

When it is desired to angularly move the supporting member with respect to the plate 23 one end or the other of said mem-. hers is pivoted to one of the ears 25 .or 27 according to the position. it'is desired to move the supporting member 30.' Aplurality of pins 42, 42, are provided for this purpose. The pins -42 serve to connect the threaded members 26 and 28 to the ears 25 and 27, respectively, and when extended through the cars 25 and 27 may engage apertures in the lower portion of the arms 31, 31, to hold the supporting member 30 in a stationary position parallel to the plate 23. When either one or the other of the pins 42 is disengaged from the respective aperture in one of the arms 31, the supporting member 30 may be tilted about the other pin by rotating the handle 40 and one of the threaded rods 33 opposite the pivot about which it is desired topivot the supporting member 30.

A motor is attachedto the top portion of the supporting member 30 by any suitable means, said means herein being shown as cap screws of an ordinary type. The motor 45 may be of any well known type, but is herein preferably shown as an electric motor of an ordinary type provided with an armature shaft'46. A tubular supporting arm 47 is fixed to one side of the motor 45 and projects forwardly therefrom parallel to the armature shaft 46.

A drilling head 48 is trunnioned on a member 49 on the forward end of the tubular supporting arm 47 so as to be angularly movable with respect to'said arm. A strap 50 is provided to hold the drilling head 48 in various desirable positions with respect to the tubular arm 47, said straps being attached to said drilling head and tubular arm by nuts and bolts generally indicated at 51.

The drilling mechanism 11 and drilling head 48 is of an ordinary construction well known to those skilled in the art so will not herein'be described in detail. A gear (not shown) is journaled in the drilling head 43 and has a threaded shaft 53 passing through its hub and feathered therein so that said shaft may move through .said gear for substantially its entirelength. Threaded jaws (not shown herein since they are no part of my invention) are provided on the drilling head 48 to engage the threaded shaft 53 to move said shaft translationally with respect to the drilling head 48 to feed a drill 54 held on the forward end of said shaft in a usual manner into the material it is desired to drill. A hand operated disc'55 is provided to engage or disengage the aforementioned jaws with the threaded shaft 53 whilesuitable frictional control means (not shown) controlled by a suitable hand wheel 56 is provided tostop feeding or translational movement of the threaded shaft 53 on overload of the drilling mechanism.

A shaft 60 is journaled within the tubular arm 47 for feeding and rotating the drill 54 through a. suitable system. of gearing not herein shown since it is no part of my present invention. The shaft 60 is driven from the motor 45 by means of a suitable geared reduction which herein comprises a spur gear 61 keyed on said shaft driven by a pin ion 62 lreyed on the armature shaft 46. f

In'Figure 2 a plurality of drilling devices. are shown mounted on the forward portion of amine locomotive simultaneously drilling a plurality of holes in a mine wall in the usual manner. A bracket 65 is providedon the forward end of the locomotive to serve as a support for an additional arm '12 to support the drilling mechanism thereon when desired as is partially shown in dotted lines. When it is desired to travel about the mine the arms 12 are folded onto the forward portion of the locomotive as is shown in dotted lines in Figure 2 so that the loco-V motive which supports and transports the drilling mechanism may also be used to haul cars about the mine. I

It may now be seen that I have provided a new and improved drilling mechanism and support therefor of a new and improved construction which may be detachably connectible with a mine locomotive, or a similar track-mounted power vehicle, such as 'a truck, todrill holes in a mine wall at various angles and positions with respect thereto, and that said support and drilling mechanism is of a light and compact design and is so arranged that it will take up a minimum of room while being transported about the mine. 7
